Technical Field
The utility model belongs to the technical field of medical instrument and specifically relates to a make things convenient for ureteral stent to pull out device by oneself.
Background
The ureteral stent tube is a hollow tube made of high polymer materials, and is conventionally kept in the ureteral stent tube after kidney stones, ureteral stones, hydronephrosis, kidney transplantation, kidney and ureteral tumors, ureteral stenosis and the like so as to ensure that urine is drained from the kidney to the bladder, avoid the ureteral stenosis, urinary fistula and other conditions, and be more favorable for discharging stones for patients with stones. Therefore, the purpose of indwelling the ureteral stent tube is to drain the urine of the kidney and temporarily relieve the obstruction of the upper urinary tract, and the indwelling ureteral stent tube is the most widely applied mode of the external urinary surgery. At present, no ureteral stent tube can be permanently remained in a body, so that the ureteral stent tube needs to be pulled out by a cystoscope operation after a period of use. Many patients ignore the doctor's notice or some patients are unaware of the replacement cycle or even the replacement of the ureteral stent. When the patient is in a bad visit, the patient can find that the ureteral stent is full of stones, and the doctor needs to risk the ureter to be torn or detached when removing the ureteral stent, which is very dangerous for both doctors and patients. To solve this problem, utility model No. 201721903947.9 discloses a ureteral stent with a pull wire, which can release the pull wire through a degradable material to make it leak out of the body, so as to pull out the stent. It has 3 disadvantages: 1. the bracket tube is required to be manufactured independently, and the bracket tube cannot be used commonly with the existing ureteral bracket tube; 2. the degradation product is a dropper container and a control valve is used in a human body, and the specific manufacture and operation are difficult to realize; 3. the traction line is not easy to leak out of the body, and male patients are not easy to discharge by themselves.
SUMMERY OF THE UTILITY MODEL
Can be difficult to realize and the difficult external problem that spills of pull wire with current ureteral stent tube is general among the solution prior art, preparation and operation, the utility model provides a make things convenient for ureteral stent tube to pull out device by oneself, it can be general with current ureteral stent tube, simple manufacture, convenient operation and have the pull wire and conveniently spill external advantage.
The utility model discloses a realize above-mentioned purpose, realize through following technical scheme: the utility model provides a make things convenient for device that ureteral stent tube pulled out by oneself, includes degradable casing, sets up the traction block in the degradable casing, fixes the one end that sets up the pull wire on the traction block, and the middle part of pull wire is located degradable casing, the other end of pull wire and the end connection of ureteral stent tube.
In order to further achieve the purpose, the technical scheme is as follows: the traction block is in a gyro shape, a spherical shape or a conical shape. The degradable shell is cylindrical and is arranged at the end part of the ureteral stent. The length of the traction wire is 25-35 cm. The degradable shell is provided with a first connecting hole, the traction block is provided with a second connecting hole, and the first connecting hole is communicated with the second connecting hole.
The utility model has the advantages that: the utility model discloses a degradable casing uses degradable material, according to the time of the ratio decision degradation of degradable material, degradable shell degradation back, pull wire and traction block release, at the urination in-process, the traction block relies on its volume and dead weight, can be driven to the urethral orifice by the urine, and pull block and pull wire are along with the urethral orifice of urine discharge, the utility model discloses make people can drag the pull wire and pull out ureteral stent by oneself, need not other apparatus, convenient to use, safety and sanitation has reduced the misery that the patient pulled out ureteral stent, can not bring infection and damage for the patient, and can with current ureteral stent general, simple manufacture and have the convenient external advantage of pull wire.
